Charles was born in 1707. He became a priest in the Church of England. On May 21 1738 he had a conversion experience which changed his life. His well-known hymn "O for a thousand tongues to sing my great Redeemer's praise" was probably written during the following year.
He joined his brother John, and others, in an evangelical movement that led eventually to the founding of the Methodist Church.
Charles Wesley is particularly noted for his work as a Christian poet, and he wrote more than 6,000 hymns. One of his sons, Samuel became a musician and organist, and a grandson of Charles - Samuel Sebastian Wesley - became an organist and composed music for the church. ... Charles Wesley passed away in 1788.
